Question

Observe the given table and draw a graph.

From the graph, the unit rate per kg will be .

• A. ₹15
• B. ₹20
• C. ₹15
• D. ₹10

Answer 1

The correct option is C ₹15

On a graph, let's represent the prices on the y-axis and weight on the x-axis.

The table given in the question is:

So, the points to be plotted on a graph from the given table are: (10,150), (20,300), (30,450), (40,600).

Now, by plotting the points, the obtained graph is:

Now, we know,
Unit rate = Constant of proportionality

From the graph, we get,
$\text{Unit rate}=\frac{150}{10}=\frac{300}{20}=\frac{450}{30}=\frac{600}{40}=15$

∴ Unit rate per kg is ₹15.
